A CSA is a season's share in the harvest of the farm with weekly boxes of organically grown produce that has been out of the ground or off the stalk for less than 4 hours. You will benefit enormously from eating these vegetables and having knowledge that they were grown in the healthiest manner for you and the soil.
When you join the CSA you will be supporting the local economy, decreasing oil dependence, and expressing your power to build community. Members of the CSA help the farmer to buy water, tools, and seeds and to pay for the lease on the land and equipment.
